...and fortunately for us computer graphics is the ultimate controlled environment.
I was just reviewing some of the earlier contests, like the Losts Worlds contest, and while none of them would have fit very well 'as is' as a splash screen all of them could have been made to work well by using a contour mask/matte. Granted, that mask would be a bit hard to make directly in A:M but with tools like A:M Composite's Exposure or HSE (Hue, Saturation, Exposure) Post Plugins those masks aren't as hard to make as they once would have been.
